我正在开发一个应用程序，其中我必须同时录制一首歌曲和一个wav文件.我正在播放iPod音乐库中的歌曲，并在视图控制器上放置了一个按钮， WAV文件开始，但是当我开始使用AVAudioRecorder录制时，WAV文件停止工作. 这是我的ipod音乐库的代码:-

I'm developing an App in which i have to record a song and a wav file at a same time.I'm playing song from iPod Music libraries and on a view controller i have placed a button on click of which an wav file starts but when i start recording using AVAudioRecorder,my wav file stop working. This is my ipod music library's code:-

- (void) mediaPicker: (MPMediaPickerController *) mediaPicker didPickMediaItems: (MPMediaItemCollection *) collection { MPMediaItem *item = [[collection items] objectAtIndex:0]; NSURL *url = [item valueForProperty:MPMediaItemPropertyAssetURL]; [self dismissModalViewControllerAnimated: YES]; // Play the item using AVPlayer AVPlayerItem *playerItem = [[AVPlayerItem alloc] initWithURL:url]; player = [[AVPlayer alloc] initWithPlayerItem:playerItem]; [player play]; }

这是我播放wav文件的代码:-

and this is my code by which i m playing wav file:-

-(void)playAudio:(NSString *)path { SystemSoundID soundIDWav; NSString *sound = [NSString stringWithFormat:@"%@%@",[[NSBundle mainBundle] resourcePath], @"/wavFile.wav"]; NSURL *filePath = [NSURL fileURLWithPath:path isDirectory:NO]; AudioServicesCreateSystemSoundID((__bridge CFURLRef)filePath, &soundIDWav); AudioServicesPlaySystemSound(soundIDWav); }

我正在通过AVAudioRecorder录制这两个... 请帮忙.谢谢...

推荐答案

创建音频会话

audioSession.delegate = self; [audioSession setCategory:AVAudioSessionCategoryPlayAndRecord error:nil]; [audioSession setActive:YES error:nil];

现在在AVAudioPlayer中播放文件，并同时开始使用AVAudioRecorder录音

Now play your file in AVAudioPlayer and at same time start recording using AVAudioRecorder
